Add Powershell script parameters

[christianhelle]

The changes here update the generated Powershell scripts to contain mandatory parameters if the operation path or query contains parameters

For example:

<#
  Request: GET /pet/{petId}
  Summary: Find pet by ID
  Description: Returns a single pet
#>
param(
   <# ID of pet to return #>
   [Parameter(Mandatory=$True)]
   [String] $petId
)

curl -X GET https://petstore3.swagger.io/api/v3/pet/$petId `
  -H 'Accept: application/json' `
  -H 'Content-Type: application/json'
